A Forum for LLVM Developers

The meeting serves as a forum for LLVM, Clang, LLDB and other LLVM project developers and users to get acquainted, learn how LLVM is used, and exchange ideas about LLVM and its (potential) applications.

Two Full Days of Program

The conference will be two full days that include technical talks, BoFs, hacker’s lab, tutorials, a poster session and a reception.

Broad Target Audience

Active developers of projects in the LLVM Umbrella; Anyone interested in using these as part of another project; Compiler, programming language, and runtime enthusiasts; Those interested in using compiler and toolchain technology in novel and interesting ways.


The detailed program including author names, affiliation and abstracts can be found here.
